Problems solved by technology

For ships using water jet propulsion, a flow channel area is added at the bottom of the stern. If the traditional method is used to make the overall shape of the stern hull including the flow channel smooth, it is impossible to use the existing ship design software. For example, through the original manual stakeout, although the stakeout work can be completed, the workload is large and the smoothing accuracy is low, and manual stakeout cannot generate profile data for subsequent design modeling

Abstract

The invention provides a method for setting out the profile of the stern with runners. By splitting the staked profiles of the runners, they are smoothed separately, and then finishing and splicing to obtain a complete profile of the stern with runners. The accuracy of stakeout reduces the difficulty of stakeout work, improves the efficiency of stakeout work, and ensures the smooth progress of subsequent design and modeling work.

Description

technical field [0001] The invention relates to the technical field of lofting and smoothing of ship hull lines, in particular to a method for setting out lines of a stern with flow channels. Background technique [0002] According to the theoretical hull curve obtained from the experimental design of the mother ship and the ship model tank, there will be local uneven areas before lofting treatment. If the hull is constructed according to this model line, the hull plate will be uneven and unsightly , and will lead to an increase in the navigation resistance of the underwater part. Therefore, before the design and construction of the ship, three-way smoothing is performed on the hull shape line to facilitate subsequent hull structure lofting and structural design modeling. [0003] In the field of ships, water jet propulsion is a special propulsion method. It sucks water into the flow channel through the suction port at the bottom of the stern, and then ejects the reaction f...
